Ryan Lochte and other U.S. swimmer caught on camera fighting at Brazilian gas station

A Brazilian police source told ABC News that one of the U.S. swimmers was caught on video damaging a bathroom door and fighting with a security guard at a gas station the same night of their alleged robbery.

Olympic swimmer Ryan Lochte claimed on Sunday that he and three other U.S. swimmers were robbed in a taxi headed for the Olympic Village in Rio.

Lochte told NBC News' Matt Lauer Wednesday night that the swimmers used a restroom at a gas station and when they got back to their taxi, the driver didn't move. That's when two men approached with guns and badges and told them to get out and get down, Lochte said.

Police told ABC News that the swimmers "offered 100 reals and $20" to compensate for the damage.
